From 8.0 to 8.1

NOTE: GitLab 8.0 introduced several significant changes related to installation and configuration which are not duplicated here. Be sure you're already running a working version of 8.0 before proceeding with this guide.

0. Double-check your Git version

This notice applies only to /usr/local/bin/git

If you compiled Git from source on your GitLab server then please double-check that you are using a version that protects against CVE-2014-9390. For six months after this vulnerability became known the GitLab installation guide still contained instructions that would install the outdated, 'vulnerable' Git version 2.1.2.

Run the following command to get your current Git version:

/usr/local/bin/git --version

If you see 'No such file or directory' then you did not install Git according to the outdated instructions from the GitLab installation guide and you can go to the next step 'Stop server' below.

If you see a version string then it should be v1.8.5.6, v1.9.5, v2.0.5, v2.1.4, v2.2.1 or newer. You can use the instructions in the GitLab source installation guide to install a newer version of Git.

1. Stop server

sudo service gitlab stop

2. Backup

cd /home/git/gitlab
sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production

3. Get latest code

sudo -u git -H git fetch --all
sudo -u git -H git checkout -- db/schema.rb # local changes will be restored automatically

For GitLab Community Edition:

sudo -u git -H git checkout 8-1-stable

OR

For GitLab Enterprise Edition:

sudo -u git -H git checkout 8-1-stable-ee

4. Update gitlab-shell

cd /home/git/gitlab-shell
sudo -u git -H git fetch
sudo -u git -H git checkout v2.6.5

5. Update gitlab-git-http-server

cd /home/git/gitlab-git-http-server
sudo -u git -H git fetch origin
sudo -u git -H git checkout 0.3.0
sudo -u git -H make

6. Install libs, migrations, etc.

cd /home/git/gitlab

# MySQL installations (note: the line below states '--without postgres')
sudo -u git -H bundle install --without postgres development test --deployment

# PostgreSQL installations (note: the line below states '--without mysql')
sudo -u git -H bundle install --without mysql development test --deployment

# Run database migrations
sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production

# Clean up assets and cache
sudo -u git -H bundle exec rake assets:clean assets:precompile cache:clear RAILS_ENV=production

# Update init.d script
sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab

For Ubuntu 16.04.1 LTS:

sudo systemctl daemon-reload

7. Update configuration files

New configuration options for gitlab.yml

There are new configuration options available for gitlab.yml. View them with the command below and apply them manually to your current gitlab.yml:

git diff origin/8-0-stable:config/gitlab.yml.example origin/8-1-stable:config/gitlab.yml.example

Nginx configuration

View changes between the previous recommended Nginx configuration and the current one:

# For HTTPS configurations
git diff origin/8-0-stable:lib/support/nginx/gitlab-ssl origin/8-1-stable:lib/support/nginx/gitlab-ssl

# For HTTP configurations
git diff origin/8-0-stable:lib/support/nginx/gitlab origin/8-1-stable:lib/support/nginx/gitlab

If you are using Apache instead of NGINX please see the updated Apache templates. Also note that because Apache does not support upstreams behind Unix sockets you will need to let gitlab-git-http-server listen on a TCP port. You can do this via /etc/default/gitlab.

8. Start application

sudo service gitlab start
sudo service nginx restart

9. Check application status

Check if GitLab and its environment are configured correctly:

sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production

To make sure you didn't miss anything run a more thorough check:

sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production

If all items are green, then congratulations, the upgrade is complete!

Things went south? Revert to previous version (8.0)

1. Revert the code to the previous version

Follow the upgrade guide from 7.14 to 8.0, except for the database migration (The backup is already migrated to the previous version)

2. Restore from the backup

cd /home/git/gitlab
sudo -u git -H bundle exec rake gitlab:backup:restore RAILS_ENV=production

If you have more than one backup *.tar file(s) please add BACKUP=timestamp_of_backup to the command above.

Troubleshooting

"You appear to have cloned an empty repository."

See the 7.14 to 8.0 update guide.
